Applications of tungsten

Are you interested in the use of tungsten? Supplier KMZ offers to buy tungsten and its alloys at economical price. Supplier guaranteed timely delivery at any address specified by the consumer.

Application for hard alloys

Tungsten carbide is produced by «cementing» very hard monocarbide WC grains in a binder matrix of tough cobalt alloy or Nickel by liquid-phase sintering. Cemented carbides combine the high hardness and strength of metallic carbides (WC, TiC, TaC) or carbonitrides (e.g. TiCN) with the toughness and ductility of the binder metal alloy (Co, Ni, Fe), in which solid particles are evenly dispersed with the formation of the metal composite. Tungsten carbides combine the high hardness and strength with a satisfactory viscosity. Their use is important in a wide range of temperatures;

Alloying steels

Tungsten is among the first alloying elements systematically studied and used to improve steel properties, for example, to increase the hardness, efficiency and speed of cutting. Of all the produce of tungsten, about 20% is used for alloying.

Application in electrical engineering

The production of electrodes and incandescent lamps. About 4% of the annual tungsten production is consumed by the lighting industry. Despite the wide spread of LED lamps the largest market is still for incandescent lamps (in 2007, produced about 12 billion bulbs). Tungsten filament best due to the extremely high melting temperature (approximately 3695 K), lowest vapour pressure, high stiffness and excellent resistance to creep at elevated temperatures.

Electronic emitters

Tungsten is practically the only material used for electron emitters. Its advantage is its extremely low vapour pressure even at high temperatures. This property is also important for electrical contact materials. Therefore, this metal is one of the most important components in modern integrated circuits, a copper-tungsten radiators are used to remove heat from microelectronic devices.
